   OmniScrypt tools: shared stylesheet
   ---------------------------------------------------------------------------
   Loaded by every tool, after shared/css/tailwind.build.css and before the
   tool's own css/tool.css. Everything that makes the tools look and feel the
   same lives here; a tool's own file only adds what exists in that tool.

   The look is EventHarmon!'s.

   Sections:
     1. Tokens
     2. Base typography
     3. Surfaces (slabs, wells, buttons, pills)
     4. Popups (every popup in every tool)
     5. Toast
     6. Ambient orbs and scrollbars
